Title: Hydrobromination process
IPC: C07C17/08
Filed: 1964-12-24
Abstract: Alkyl bromides are prepared by the free radical addition of hydrogen bromide to alphaolefins containing at least three carbon atoms in the molecule by a process which comprises:  (a)  Reacting in a first reaction zone said alpha-olefins with from 75-95 mole per cent of HBr in the presence of a free radical initiator to cause partial conversion of the olefins to alkyl bromides to a completeness level of 75-95%, and  (b)  Reacting in one or more subsequent reaction zones said partially converted reaction product with additional excess HBr to complete the conversion reaction, each of the reaction steps being carried out at 20-60 DEG  F. and for a period of 1-15 minutes.  The free radical initiator is desirably an oxonide formed in situ by pre-treating the alpha-olefin with ozone.  Comparative examples illustrate a single-stage process and processes in which the first stage conversion exceeds 95%. The products may be reacted with NaCN or (CH3)2NH to give the corresponding nitrile or amine.

Title: Apparatus for measuring the resistance to untangling of hair
IPC: G01L5/00
Filed: 1973-11-20
Abstract: 1406398 Untangling hair; brushes L'OREAL 20 Nov 1973 [20 Nov 1972] 53741/73 Headings A4K and A4V [Also in Divisions A5 and G1] An apparatus for measuring the force involved in untangling a mass of hair, comprising a handle 1, a carding member 2 capable of limited movement from an original position, relative to the handle, when a carding force is applied, leaf spring 12 for returning the carding member to the original position when the force is removed, and a counter registering the amplitude of said relative movement. A comb 2 is held by member 3 to the end 4a of a rod (4) passing into the handle 1 through a hole 5 and through a universal joint 6 comprising a shaft 7 perpendicular to the longitudinal plane of the comb 2, and supported in handle 1, and a shaft 8 perpendicular to the shaft 7 and pivotable inside member 6. The rod (4) is biased by spring 9 against the weight of the comb 2. End 4b of rod (4), remote from the comb has a half flat 10 held by spring 9 against friction roller 11, and is hook-shaped, the bent-back tip carrying a leaf spring (12) Fig. 2 (not shown) against which the end of adjusting screw (13) bears. Various positions of screw (13) are possible to adjust the return force of spring (12). The roller 11 rotates shaft 14 which passes through counter 15 to a ratchet wheel 16 co-operating with pawl 17, to  permit rotation of the ratchet wheel in one direction only to turn the counter 15. Knob 19 is depressed to release the pawl to reset the counter. When used to untangle hair, comb 2 tends to rotate shaft 8, displacing end 4b of rod (4), thereby rotating roller 11 and shaft 14 of counter 15 to record a measurement indicating the force required. Subsequent strokes add to the counter until untangling is achieved, when resistance ceases. A brush may be used instead of a comb. In an alternative embodiment, Figs. 3, 4, (not shown), a brush (22) is supported by a brace (23), one end (23a) of which is attached to the end (24a) of shaft (24) passing into handle (21) through bearing (25). A half flat (30) Fig. 5 (not shown) carries an angle member (31), one arm of which is fixed to flat (30), the other arm carrying a series of leaf springs (32). A screw (33) through handle (21) abuts a chosen one of the leaf springs (32) which have different flexural stiffnesses to vary the return force on the brush. End (24b) of shaft (24) is fixed to a ratchet wheel (36) driving a pawl support (38) through a pawl (37), the pawl support (38) being fixed to shaft (41) attached to a pinion (45) of gear train (45, 46, 48, 49) to give a step-up to the rotation of the counter (35) driven by shaft (34) attached to gear (49).

In the embodiment shown the vehicle comprises guide wheel assemblies as 24, 25 each comprising a respective roller 83, 84 and a guide wheel 29, 30 for engaging guide walls 43, 44. Alternative guide wheel assemblies are also described. In a second embodiment the guide walls 43, 44 are omitted and the vehicle is guided by wheels engaging both sides of an upright guide rail extending centrally of the guideway. The rail structures 49, 55, 61 are supported on posts spaced along the track. Instead of wheeled vehicles it is stated that ground effect vehicles may be used. At locations where two branches of a guideway merge into one a passive switch is employed wherein the actuating mechanism 74 is omitted and the rail structure 61 is biased to its first position by a leaf spring, the structure 61 being automatically pivoted to its correct position by the passage of a vehicle through the switch. Fig. 19 shows a control system comprising mutually insulated signal rails 104 and a ground rail 103 whereby a vehicle detection circuit 109 can detect the presence of a vehicle 12 and activate a communication circuit 110 to interrogate a register unit 106 on the vehicle by way of a vehicle borne communication circuit 107 as to its identification and programmed route, such information being used to set the switch 10 to the appropriate position for the passage of the vehicle.

Filed: 1974-12-24
Abstract: 1472100 Ultrasonic imaging system ROHE SCIENTIFIC CORP 24 Dec 1974 55860/74 Heading H4F [Also in Division G1] In an ultrasonic pulse-echo system, e.g. for medical diagnosis, echo signals from a scanning transducer are stored in a scan converter then read out to a display device, the duration of the storage and read-out periods each being a given fraction of the duration of a complete raster scan of the display device. A transducer with two translational and one rotational scan components is used in the embodiment described, the echo signals being stored in the scan converter at positions related to the transducer position when the converter is in its "write" mode. During the "read" mode the stored data provides a display on a conventional TV monitor. The TV line and frame blanking pulses are fed to the clock and reset inputs respectively of a counter. Every n (e.g. n=7) counts the counter causes a flip-flop to change state and this switches the converter from the "write" to the "read" mode or vice versa. The mode duration is thus n TV lines. By choosing n such that an odd number of mode changes occur within a complete TV field scan, proper interlacing of the "write" and "read" periods of consecutive TV fields is ensured. A display CRT with a long-persistence phosphor is used to avoid image flicker.

Abstract: 1275987 Offshore structures COMPAGNIE FRANCAISE D'ENTREPRISES METALLIQUES 17 Nov 1969 [21 Nov 1968] 56164/69 Heading E1H A column 1 connected to a base 2 on the sea bed 3 by a universal joint 4 has a buoyancy compartment 6 and a compartment 8 wherein liquid hydrocarbon extracted from a well 7 can be stored, the compartment 6 being charged with a quantity of said hydrocarbon that is proportional to the quantity in the compartment 8 so as to tender the upthrust on the column substantially constant and thereby obviate excessive upward loading of the base and joint. When the hydrocarbon is being drawn from the well into the compartment 8 by a pump 9 through pipes 10, 11 a corresponding quantity of sea water is expelled through openings 12, and a proportion of the hydrocarbon enters the compartment 6 through conduits 13, 14 and valve 15 controlled by a servo-device 26 in accordance with electric signals from level-measuring means 21, 22. A pumping means 18 controlled by a servo-device 25 returns hydrocarbon to the compartment 8 when hydrocarbon is discharged from the latter through conduits 16, 17 to provide compensation for an equal quantity of water reentering the compartment 8 through the openings 12. A tubular shaft 32 for the pipe 10 may be replaced by tubular shafts disposed externally of the column, Figs. 4 to 6 (not shown). Alternatively, several tubular shafts may be provided within the column. Sea water may be used to charge the compartment 6 (instead of the hydrocarbon). In another embodiment, Fig. 8, the column is fully submerged and the compartment 6 is replaced by an air-filled machinery-compartment 46 with access means 47 for a diver. A pocket 36 of compressed gas is provided above the liquid hydrocarbon 38 by a purification unit 42 associated with a pump 41 for the incoming hydrocarbon. A unit 45 renders the pressure in the pocket 36 constant while hydrocarbon is being received through a conduit 44 or discharged through a conduit 50. At similar arrangement may be employed in a column extending above the free-surface of the water, Fig. 7 (not shown). The means 47 may be replaced by an access and ventilation column pivotally attached to the head of the compartment 46, Fig. 9 (not shown).
